How do I format a C# decimal to remove extra following 0's?

Question

I want to format a string as a decimal, but the decimal contains some following zeros after the decimal. How do I format it such that those meaningless 0\'s disappear?

Answer 1

Somewhat hackish, but this should work:

decimal a = 100.00M;
string strNumber = string.Format("{0}", a);
Console.WriteLine(strNumber.Contains('.') ? strNumber.TrimEnd('0').TrimEnd('.') : strNumber);
